And, you know, a lot of people have been concerned about video-based training for kids with autism because of the concern that they will fall into a pattern of -- it ` s called echolalia, and that is the repeating that you ` re talking about.

One theory of sleep is that dreams are just a nighttime hallucination that the brain simply strings together into a meaningful narrative, which means that all of the sleep talking Liz is hearing on the video playback is just a series of words, echolalia from the day tossed together with her own mind making connections.

All I do is feebly hack away at trying -- emphasis on trying -- to capture some version of "reality" that will speak for itself, including the echolalia of the very media influence that filters it by the act of recording it.
